If the preliminary test is reactive, the result is considered a preliminary positive. To confirm the result, the lab will use a more sophisticated test called the HIV differentiate assay and possibly the NAT. If the confirmatory tests are both nonreactive, you can be assured with a high level...
8,9 If supplemental testing for HIV-1/HIV-2 antibodies is nonreactive or indeterminate (or if acute HIV infection or recent exposure is suspected or reported), an HIV-1 nucleic acid test is recommended to differentiate acute HIV-1 infection from a false-positive test result.8,9 Antigen/...
An HIV genotype test is best used to screen before start of treatment and for those with failure of their first one or two treatment regimens. HIV phenotype assay - HIV phenotype measures the actual amount of drug it takes to block infection by the patient's virus. The HIV phenotype is ...

Since their safety profile is more than demonstrated, smaller, more directed experimental medicine vaccine trials (EMVT) can be performed to answer more directed scientific questions to screen for specific immunogens. This new discovery methods could accelerate vaccine science by testing multiple ...
J-Lat 10.6 cells were treated with the top five candidates, as in the screen-based approach, and incubated with Ghost Dye Violet (450), which is a free amine-reactive viability dye used to discriminate viable from nonviable cells using flow cytometry. None of the compounds showed any ...
The early infant diagnostic (EID) program for HIV aims to screen all HIV-exposed children during the first postnatal visit (at 4–6 weeks) for timely treatment initiation for every infected child [1,2]. Nevertheless, less than 20% of HIV-exposed infants in resource-limited settings (RLSs) ...
